get_connection_status

Check whether any browser clients are connected to the feedback server, so you can confirm feedback collection is available before sending annotations.

Instructions

TDQS

B3.4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. The verb 'Check' implies a non-mutating read, and the scope ('any browser clients ... connected to the feedback server') is stated, but it never discloses the return shape (boolean, client count, or list) despite no output schema existing. Adequate but incomplete for a tool with zero annotation coverage.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded sentence with no filler. Every word earns its place, and the subject of the check is immediately clear.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a trivial 0-param, no-output-schema tool this is close to sufficient, but with no annotations and no output schema the description should at least indicate what 'connected' returns so the agent knows how to interpret the response. The purpose is covered; the result contract is not.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool takes zero parameters, so there are no parameter semantics to explain; the baseline for a 0-param tool is 4. The description correctly implies the call is argument-free.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource: 'Check if any browser clients are connected to the feedback server.' An agent can tell this is a connectivity probe rather than an action tool. It does not explicitly contrast itself with the closely related sibling wait_for_browser_feedback, which is the main gap.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No when-to-use guidance is given. The description does not say whether this is a preflight check before wait_for_browser_feedback, whether it polls, or how it relates to the other 11 siblings. Usage must be inferred entirely from the name.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
